David Steinberg has directed so many sitcoms that it seemed logical to ask him: How are sitcoms doing these days?

“They’re not doing well,” he said on the phone from California the other day. “And it’s not that the talent isn’t there. The talent is definitely there … [It’s that] sitcoms have been around for a long time inside the same four walls, and I think people are just too used to them.

“And that’s why ‘Curb Your Enthusiasm’ sort of broke through, it didn’t look like a normal sitcom.” It’s not surprising that Steinberg is partial to Larry David’s HBO comedy series since he’s directed three episodes. In addition, David is the second of six guests who Steinberg interviews on the subject of comedy in his new, six-part series premiering tomorrow night at 10 on TV Land – “Sit Down Comedy with David Steinberg.”

His inaugural guest tomorrow is Mike Myers. David appears next Wednesday. The other four guests are Martin Short, Bob Newhart, Jon Lovitz and George Lopez.

With more than 40 years in the business, Steinberg, 63, emerges on his new show as a kind of professor of comedy. As a comedian in the 1960s and ’70s, he was a fixture on TV variety shows.

Since 1981, he has compiled a long list of credits as a director, including episodes of “Newhart,” “The Golden Girls,” “Designing Women,” “Evening Shade,” “Mad About You,” “It’s Garry Shandling’s Show,” “Friends” and more than a dozen others.

“I feel like the Zelig of comedians,” said Steinberg, referring to the chameleon-like character invented by Woody Allen.

His new series is kind of like “Inside the Actors Studio,” except funnier.

“James Lipton is a lot more prepared than I am, which you’ll see if you watch the show,” Steinberg said. “I get so much wrong, it’s unbelievable.”

In the premiere episode, Steinberg makes so many errors at the outset of his interview with Myers that it becomes a running gag.

Of all his six guests, Steinberg was acquainted least with George Lopez. “[His] life is brutally dark,” Steinberg said. “I had no idea, and as he unraveled what his life was – you know, his father leaving the day he was born, his mother being on crack – and then turning all that into humor right there in front of me, that was phenomenal for me and exciting.”
